A 284ft wooden skyscraper built from 1,200 bespoke pieces tests fire safety limits in Milwaukee; a decaying Amsterdam crane track transforms into glass offices; a needle-thin tower stacks 28 apartments onto a 21ft-wide plot in Melbourne, Australia.

Host Mike Davidson goes to the remote Atacama Desert in Chile; at observatory ALMA he works alongside the expert team as they repair some of the world's biggest antennas.

Lord Foster's five-winged steel towers cool Abu Dhabi's national museum naturally. Robots 3D-print a steel bridge in Amsterdam & a concrete tower in Switzerland. And in Sydney, engineers pump out the harbour to build a fish market.

Mike Davidson goes to the biggest automated package sorting facility in the world, UPS Worldport in Louisville, Kentucky; two million packages go through here every day.

A mission to haul hefty cargo across Switzerland to the Netherlands, going through four countries with critical repairs at every turn.

Traveling the Dordogne River via traditional boats through the green heart of southwest France; drinking wine and hunting for truffles; riding a luxury cruiser to a lighthouse built for a king.

The view from above reveals baffling behavior from one of the ocean's fastest fish; whales with a strange, aquatic accessorizing habit; a confounding congregation of sharks down under; a perplexing collection of circles decorating the seabed.

A salvage maestro returns to raise more valuable tropical hardwood trying not to wreck his own boat in the process; the multimillion dollar operation to salvage America's biggest shipwreck.

A member of the Osage Nation investigates the series of murders and unexplained deaths that struck the oil-rich tribe in the 1920s.

In less than 200 years, the Aztecs rose from nomadic origins to build the powerful empire of Tenochtitlan. Combining archaeology and stunning 3D reconstructions, this series reveals the rise and fall of a remarkable civilization.

Uncover the sinister ways that dictators convince their followers to worship them as heroes; watch how they weave mythical narratives around their abilities, selling themselves as saviors who should hold absolute power over the people.

Rumoured to be the cleanest river in Europe, few dispute it's the coldest; cascading down from the Dinaric Alps in Serbia, it soon crosses the border into Bosnia-Herzegovina, where marine biologist and fisherman Sanel Riđanović casts for salmon.

The view from above reveals a derelict complex of pod-like structures with seemingly alien origins; a bewildering concrete construction in the mountains of Bosnia; a puzzling collection of out of place shapes discarded in the wilds of Greenland.

The team must remove thousands of wrecked cars from the hull before it becomes an environmental disaster; repairing a vessel before the waters of the River Solent flood the hull.
